There has been one failure so far: https://autobuilder.yocto.io/builders/build-appliance/builds/1201/steps/BuildImages_1/logs/stdio I suspect we need to tweak the do_populate_poky_src task in the build- appliance-image recipe given the kernel devsrc change. Other things are still building. Will reply if anything else comes up.
